The LBA-ECO program is one of several international research components under the Brazilian-led Large Scale Biosphere?Atmosphere Experiment in Amazonia (LBA). The field-oriented research activities of this study are organized along transects and include a set of primary field sites, where the major objective is to study land-use change and ecosystem dynamics, and a smaller set of 15 operational eddy flux tower sites, where the major objective is to quantify net exchange of CO2 with the atmosphere. To supplement these studies and help to address issues of fine-scale spatial heterogeneity and scaling, high-resolution satellite imagery (IKONOS, 1?4 m) have been acquired over some of these study sites. This paper begins with a description of the acquisition strategy and IKONOS holdings for LBA. This section is followed with a review of some of the most promising new applications of these data in LBA. |

This study evaluated forage, supplement, and total (forage + supplement) dry matter intake (DML, expressed as kg/day and as percentage of average live weight, %ALW) of Nellore steers in different production systems, including a Cajanus cajan (Pigeon pea) legume-grass intercropped pasture by using external (titanium dioxide, TiO») and internal (indigestible neutral detergent fiber, INDF) markers. The experiment was carried out at Embrapa Southeast Livestock, São Carlos, SP, Brazil, in the rainy (January) and dry (July) seasons of 2021. Eighteen animals Nellore steers were randomly distributed into three treatments with three replications (1.5 ha paddocks each): 1) degraded pasture of Urochloa decumbens cv. Basilisk (DEG); 2) Intercropped legume-grass pasture composed by U. decumbens cv. Basilisk, U. brizantha cv. Marandu and Cajanus cajan cv. BRS Mandarin limed and fertilized with P, K, S, micronutrients (INT) and 3) mixture pasture of U. decumbens cv. Basilisk and U. brizantha cv. Marandu limed and fertilized with P, K, S, micronutrients and 200 kg N-urea ha! year (REC). The statistical model considered treatment and season as fixed effects, and the treatmentxseason interaction was tested. Data were submitted to analysis of variance (PROC MIXED) and means were compared by the Fisher test at 5%. Significant treatmentxseason interaction was found (P < 0.05). During the rainy season lower values of forage and total DMI were found for the INT treatment when compared to REC. However, during the dry season, the treatment with Pigeon pea inclusion (INT) presented higher values of forage and total DMI. The DEG and REC system steers reduced their DMI from the rainy season to the dry season, even receiving a mineral energetic-protein supplement with urea, while the INT steers maintained DMI between seasons without receiving the energetic-protein supplement. These results highlight the potential of including Pigeon pea in pasture-based systems, especially during the dry season when tropical grasses present low nutritional quality and forage availability.
